by Krishna Ramanujan, Cornell University Associative and predictive codes in the hippocampus. Our optogenetic manipulation perturbed hippocampal sequences without affecting cell coactivity, thus selectively disrupting the predictive code. After learning, cell assemblies were reactivated, but their order was not preserved, abolishing sequential replay (right). Perturbing the predictive code had no effect on associative learning (bottom left)...
by Thamarasee Jeewandara , Medical Xpress A multiplexed diagnostic tool for detecting intraplaque and urinary MDA. We design a multiplexed diagnostic tool that includes two functions (photoacoustic imaging and urinalysis), for assessing intraplaque and urinary MDA and reliably assessing intraplaque and systematic oxidative stress in atherosclerosis.

by Stephanie Baum , Medical Xpress The relationship between vestibular loss and the risk of dementia. Credit: Scientific Reports (2023). DOI: 10.1038/s41598-023-42598-wExisting research shows a link between hearing loss and the risk of dementia, and a new study adds to growing evidence that vestibular loss can increase dementia risk as well. Results from this work,...
